Colour Capital Letters

Colour Capital Letters

[Heime]

I want to make a stand alone function that uses a different colour for capital letters 
in CamelCase names. Possibly taking code from glasses.el.

(defun color-camelcase-capital-letters ()
  "Color capital letters in CamelCase variables."
  (interactive)
  (highlight-regexp "\\(?:^\\|\\b\\)[[:upper:]][[:lower:]]*" 'hi-yellow))

What can I do ?

                         ^
                         this part will only match a the beginning of a
                         line or an empty string at the beginning or the
                         end of a word, so if you want

                             CamelCase
                             ^    ^
                             here and here

                         to be highlighted, then that won't work.

A variation of your code might be this, that highlights just the
capital letters, using `highlight-regexp's optional SUBEXP argument:
                         
 (highlight-regexp (rx word-start (group upper) (+ alnum)) 'hi-yellow 1)

Just saw this while looking through my email backlog.  This is a great
idea, but I think it can be made even better.  How about using two
colors so that subsequent /words/ in CamelCase identifiers are colored
differently?  I suspect this could be great for readibility!

Do you have any working code?  I might be tempted to try to write
something like this...

Do not have a working one yet.  I wanted to start with something quite 
simple first.  But I was planning to get subsequent words colored differently.

The purpose was about readability, particularly for Latex where one cannot use 
underscore '_'.

I looked at glasses.el, and it *already has* that feature!  Set
`glasses-separator' to an empty string and `glasses-face' to e.g. 'bold
(the symbol - name of te face).  Note: use customize-option.

If you really want to highlight every other subword, not just the
initial letters, check out this proof-of-concept implementation:
https://gitlab.com/-/snippets/3614958 .  I plan to blog about it on Nov
11.

Hth,

Re: Colour Capital Letters

[Heime]

You are using spectacles-face with a single colour.  I would like to have available
8 different colours and be able to select the colour used.  What can be done ?
